Water from a uranium ore body is naturally contaminated and cannot be used for any activity (e.g., irrigation), let alone as a source of drinking water. Oxygen is added to the naturally contaminated groundwater at the ore body, and that water is continuously re-circulated until most of the uranium is recovered.

Uranium is obtained by mining uranium containing ore known as pitchblende. The primary chemical form of the mineral concentrate that is recovered by modern mining and beneficiation techniques is triuranium octoxide (U3O8), known as yellowcake.

In Situ Leach Mining of Uranium (Updated October 2017) In 2016, 48% of world uranium mined was from ISL operations. Most uranium mining in the USA, Kazakhstan and Uzbekistan is now by in situ leach methods, also known as in situ recovery (ISR). ISL mining of uranium is undertaken in Australia, China, and Russia as well.
